The remains of a mammoth have been uncovered south of Mexico City, researchers at Mexico's National Institute for Anthropology and History said.

"For the first time in Latin America, magnetic, electric and ground-penetrating radar methods were applied in paleontology... (methods that are) commonly used in archaeological excavations to detect architectural (findings)," the institute said. Ground-penetrating radar is a technique that uses electromagnetic radiation to generate a picture of the subsurface.

Paleontologists and archaeologists worked together to use these approaches, which saved the scientists time, and helped them determine the magnitude of the discovery before the excavation process started last March.
